Costa Teguise : Underwater Sea Trek Experience
The seafloor becomes your walking path. Costa Teguise’s Underwater Sea Trek gives you a strange, memorable look at the Canary Islands from below the surface, without requiring scuba certification or swimming skill. You wear a clear helmet with panoramic vision, walk on the seabed, and breathe through an air hose linked to a bottle on a small boat above.
I like the simple underwater walking system and the way the guides stay close throughout the experience. I also like that the activity works for complete beginners, with participants ranging from young children to a 67-year-old non-swimmer. The main drawback is time: 30 minutes passes quickly, and part of that time may be used for photographs and videos rather than simply watching the fish.
The price is $88 per person, which is not cheap for half an hour in the water. Still, the small group size, personal attention, equipment, and unusual nature of the experience make it reasonable for a special family outing or first underwater adventure.
Five things to know before you book

- You walk on the actual seafloor: This is not a glass-bottom boat ride. Your feet touch the seabed while fish move around you.
- The helmet supplies your air: A hose connects your helmet to an air bottle on a small boat at the surface.
- The group is limited to eight people: That keeps the activity personal and makes it easier for guides to check on everyone.
- The experience is suitable for beginners: You do not need scuba experience, and one participant described enjoying it as a non-swimmer.
- Photos and videos cost extra: Cameras are not allowed, but the staff take underwater images that you can choose to buy afterward.
Arriving 15 minutes early in Costa Teguise

Plan to reach the meeting point 15 minutes before your starting time. That extra time matters because you will need to get organised, listen to the safety instructions, and prepare for the water.
The exact transport arrangement is not specified, so check your booking details carefully before setting out. Do not assume a hotel pickup is included. The activity is based in Costa Teguise, one of Lanzarote’s main resort areas, which makes it easy to fit into a day here if you are already staying nearby.
The small group limit of eight is a real advantage. You are not being sent underwater in a large crowd, and the guide can keep an eye on each person. That matters during a first underwater experience, especially for children or anyone who feels nervous about wearing a helmet.
The staff receive especially strong praise for their warmth and humour. Guides named Victor and Danny have been singled out for making people feel calm, while Jose Luis and his team have been praised for giving clear instructions from the moment people arrive. Names and staff can change, but the pattern is clear: the human side of this activity is one of its strongest features.

The safety talk and helmet fitting

The activity begins with an explanation of how the sea trek works. You learn how to use the helmet, how the air supply reaches you, and what to expect once you are underwater.
The helmet is the key piece of equipment. It gives you a broad view through its clear front and keeps your head surrounded by air. The weight of the helmet is supported by the water, so it does not feel as heavy underwater as you might expect. It is still an unusual sensation at first, but the guides give you time to settle.
You also wear a wetsuit. Several participants praised the quality of the suits, especially because they help take the chill off the water. This is useful even in warm weather, since you may notice the coolness more once you stop moving.
The guides are reported to check on participants continually. That is particularly helpful for anyone with anxiety or a child trying something new. One 16th birthday outing became a lasting memory because the briefing helped a nervous child feel ready to take part.
If you are uneasy, say so before entering the water. The group is small, and the guides are there to make the experience manageable, not to rush you through it.
Walking below the surface with a panoramic helmet

Once you enter the water, you walk along the seabed while the surface boat supplies air through the hose. The sensation is unlike swimming. Your feet remain below you, but the water takes much of the helmet’s weight, creating the odd feeling of moving with very little gravity.
The moon-walking comparison makes sense. You are not floating freely, but your steps feel slow and slightly strange. It takes a moment to adjust your balance and the rhythm of walking underwater.
The panoramic helmet lets you look around without turning your entire head. That gives you a better chance to notice fish beside you, below you, and in front of the group. The experience is less about speed and more about slowing down enough to watch what is happening around you.
The guides help keep the group moving together. They may use simple underwater gestures and position themselves where everyone can see them. Their job is not just technical. They also keep the mood light, which helps stop the activity from feeling like a test.
This is why the experience can suit people who are curious about the underwater world but do not want a full scuba session. You are given a direct view of the seabed without needing to manage a tank on your back or learn complex underwater skills.
Fish, sea urchins, and close-up sea life
The main reward is the contact with marine life. You can expect to see fish around the walking area, along with other underwater creatures. Several outings included chances to hold sea life such as fish and sea urchins, under the direction of the guides.
That kind of contact makes the activity more memorable, especially for children. A normal swim past a fish can be over in seconds. Here, you have time to stop, look, and understand what is nearby.
The fish are sometimes attracted to the area by the activity, so this is not a completely untouched wildlife encounter. If you are seeking a quiet, natural snorkelling experience with no human influence, this may feel too organised. If you want a reliable chance to see marine life at close range, the arrangement works well.
Visibility can vary. One participant went about a week after storms and still saw plenty of fish, but noted that the water was less clear. That is worth keeping in mind. Weather and sea conditions can affect how much detail you see, even when the activity still goes ahead.
You should also keep your expectations sensible. This is a short sea-floor walk, not a long wildlife expedition. The appeal comes from the unusual method and close contact, not from covering a large underwater area.

The photo and video part of the experience

Cameras are not allowed, which makes sense when you are wearing a helmet and connected to an air hose. Instead, a guide takes photographs and videos while you walk.
This can be a strong part of the package if you want a record of the experience. The underwater images are difficult to reproduce with a phone, and the guides sometimes add fun props or playful movements for the camera. Some families valued having pictures of children taking part, rather than relying on someone who stayed on shore.
The photo and video package is not included in the $88 price. Several participants described paying about €25 for it, though you should confirm the current charge before booking or purchasing. The purchase is optional.
There is one fair criticism: the camera work can take up too much of the short underwater session. If you would rather spend the whole time watching fish and looking around, tell the guide. You should not feel pressured to buy the images afterward, and the activity remains worthwhile without them.
My practical advice is simple. Decide before entering the water if you are interested in buying the package. If you are celebrating a birthday or taking children, the extra cost may feel worthwhile. If you care more about the experience than the record, skip it and focus on the seafloor.
How much value do you get for $88?

At $88 per person, this is a premium short activity. The 30-minute duration means the cost per minute is high when compared with a beach outing or ordinary snorkelling.
You are paying for more than time in the water. The price covers the helmet, air system, wetsuit and other equipment, guide service, instruction, and the small group format. You are also paying for an activity that is unusual and accessible to people who may not want to scuba dive.
The value is strongest when this is a highlight of your Costa Teguise stay. For a family, birthday, or first underwater adventure, the strange feeling of walking on the seabed can justify the price. If you are simply looking for the cheapest way to see fish, snorkelling will likely offer better value.
The guides also add to the value. Multiple participants described them as attentive, funny, and careful, with the best staff entertaining the group while still checking that everyone was comfortable. Good instruction is important here because the helmet and hose can look more intimidating than they feel once you are underwater.
A full refund is available if you cancel up to 24 hours ahead, and you can reserve now and pay later. Those policies make it easier to fit the activity into a changing Lanzarote schedule. Check the final booking conditions at the time you reserve.
Who will enjoy this most?

This sea trek suits adults, families, and first-time underwater explorers. The minimum age is eight, and children under eight cannot participate. Several children aged 10, 14, and 16 were described as having a great time, while an eight-year-old enjoyed the activity with close guidance.
It may also suit non-swimmers, but you should discuss any concern with the provider before booking. A 67-year-old non-swimmer completed the experience and encouraged others to try it, yet the official restrictions still matter.
Do not book if you are pregnant, have limited mobility, or have had recent surgery. The activity is not recommended in those cases. The seabed walking, helmet, water entry, and movement underwater may make it unsuitable.
You should also be comfortable with the idea of wearing a large helmet and being connected to the surface boat by a hose. The guides offer reassurance, but this remains a physical activity in the sea, not a passive sightseeing ride.
The listed instruction languages are English, Spanish, French, Italian, Portuguese, and German. That gives many participants a better chance of understanding the briefing clearly.
What can make the experience less enjoyable?

The short duration is the biggest limitation. Thirty minutes sounds adequate until you allow time for getting ready, entering the water, instructions, group movement, and photographs. If you want plenty of time to explore, this may feel too brief.
Water clarity is another variable. Storms can reduce visibility, even when fish are still present. The activity can remain fun in those conditions, but do not expect perfect underwater views every day.
The photo session may also divide opinion. Some people appreciate the large collection of images and videos, while others feel the guide spends too much time taking pictures. You can manage this by stating your preference early.
Finally, this is not a private experience by default. The group is limited to eight, which is small, but you may still share the water with other participants. If people fail to arrive, the session may become nearly private, but that is not something you should count on.
Should you book the Costa Teguise Sea Trek?
I would recommend booking this if you want a gentle first step into the underwater world, especially with children aged eight and up or with family members who do not scuba dive. The panoramic helmet, steady air supply, close guide support, and unusual moon-walking sensation make it easier to try than a traditional scuba session.
Book it as a special activity, not as a cheap way to spend an hour. At $88, the price is high for 30 minutes, but the experience is distinctive and the small group helps make the money count.
Arrive 15 minutes early, wear a swimsuit under the wetsuit, ask about current water visibility, and decide in advance if you want the optional photos and videos. If you meet the health requirements and like the idea of walking among fish rather than simply swimming past them, Costa Teguise’s sea trek is an easy activity to recommend.
